You can check out the text of the full update below, but the highlights are that there is no specific release date, but a patch to fix the cause of the original delay should be submitted to Microsoft this coming week.

As most of you know, we caught a bug that forced us to pull the release of the Xbox version of the game the day before release. It was a minor but important bug that was causing disconnects in online play. I submitted an update to attempt to fix the bug early in the week, but unfortunately it only half fixed the problem. I'm working on another fix now that I'm hoping to submit this week. Once it's confirmed fixed it shouldn't take long to push it through and get the game out. I can't promise any particular dates since I don't control that end of things, but I do know that fans are starting to get a little impatient with the lack of information. I wish I could give you more specific information, but until I have a confirmed fix, I won't be able to give a date. Hoping to have a little more information for you and fill you in on more of the details as soon as I have it!
